Never start a ride with a dead battery.
A modern road bike runs on batteries. Shifters, power pedals, lights, radar, GPS, watch, phone -- 10+ batteries from 5+ manufacturers. If any one dies mid-ride, your ride is ruined.
BikeBatt is the pre-ride readiness checklist that makes sure everything is charged, packed, and ready.
PRE-RIDE CHECKLIST
Open the app before every ride. Work through the list. Tap each item to confirm. A horizontal progress bar fills as you go -- green means ready to ride.
Devices are grouped by category: shifting, power, lights, radar, GPS, tire pressure, gear, spares and tools. Each item includes instructions for where and how to check its battery level.
BATTERY TRACKING
Log battery percentage for every electronic device on your bike. Color-coded status at a glance: green is good, orange is getting low, red means charge now.
Typical battery life is baked in for every device, so BikeBatt estimates how many hours of riding you have left. When a check gets stale, it extrapolates the likely current level from your mileage and flags devices that may be low.
Track how long replaceable batteries last. Swap a CR2032 in your SRAM shifter, log it, and over time the app learns how many days or miles each battery lasts.
SYSTEM SELECTORS
Pick your setup and the app configures the right devices, battery types, and check instructions automatically:
- Shifting: SRAM RED eTap, SRAM RED eTap AXS, Shimano Di2, Campagnolo Super Record EPS, mechanical
- Power meter: Wahoo Powrlink, Favero Assioma, Garmin Rally, SRAM Quarq, Stages, 4iiii, and more
- Rear radar: Garmin Varia RTL515 / RCT715 / RVR315, Bryton Gardia, Magene L508, Trek CarBack
- Bike computer: Garmin Edge 1050 / 1040 / 840 / 540 / 530 / Explore 2, Wahoo ELEMNT ACE / ROAM / BOLT, Hammerhead Karoo 3, Coros Dura, Bryton Rider (18 models total)
Change your setup any time from Settings.
MILEAGE TRACKING
Enter your year-to-date miles (or kilometers) from Strava or your bike computer. BikeBatt uses your riding pace to estimate when each battery will need attention, and to track battery lifespan in miles, not just days. Switch units any time.
MAINTENANCE LOG
Track when you last replaced your chain, tires, cassette, brake pads, and bar tape. A dedicated section at the bottom of the checklist keeps these separate from your pre-ride batteries.
Includes a recurring "Clean & Lube Chain" reminder (14 days by default). One tap marks it done; the app nudges you when overdue.
TIRE PRESSURE
Log front and rear PSI with a target pressure displayed as guidance. Great for beginners learning what pressure to run, and for experienced riders tracking their preference. Color feedback shows how close you are to your target.
GEAR CHECKLIST
Driving to a group ride? Never arrive and realize you forgot your shoes. The gear checklist covers cycling shoes, helmet, sunglasses, gloves, sunblock, and nutrition. Seasonal items like shoe covers are there but disabled by default -- turn them on when the weather calls for it.
SPARES AND TOOLS
Confirm your saddle bag is stocked: spare tube, CO2 cartridge, spare derailleur battery. Verify your tools: CO2 adapter, tire levers, multi-tool, mini pump. Check once, ride with confidence.
EQUIPMENT IDS
Run two power meters or a pair of identical radars? Tag each device with its ANT+ ID, Bluetooth ID, or serial number (and an optional nickname) so you always know which one you're looking at. Find these in your Wahoo, Garmin, or SRAM app under sensor details.
HOW-TO-CHECK GUIDES
Every device includes step-by-step instructions. New to electronic shifting? The app tells you which button to press and what the LED colors mean.
